GAS-BURNER.

Specification of Letters Patent.

Patented June 5, 1906.

To all. 71:71.07. it T/mg concern;

Be it known that I, WVILLIAM S. MoLEwEE, a citizen of the United States, residing at Yardley, in the county of Bucks and State of Pennsylvania, have invented certain new and useful Improvements in Gas-Burners, of which the following is a specification.

Myinvention relates to improvements in gas-burners, and particularly to burners in which a mantle is used to produce an incandescent light.

The object of my invention is to so construct the body portion of the burner that the air and gas will be more thoroughly mixed together than in the burners heretofore constructed and produce a more effective light.

A further object of my invention is to simplify the construction of the said body por-. tion of the burner by reducing the number of parts composing the same, and thus reduce the cost of manufacture.

A still further object is to construct the body portion of the burner so that globeholders may be attached at different places to accommodate diflerent styles of globes.

A still further object is to form the wiregauze cap with fluted walls to allow air to pass into the lower end of the mantle and also to hold the mantle away from the burner to prevent it turning black.

A still further object of my invention is to provide a gas-regulating device by which the flow of gas may be varied.

Referring to the drawings, Figure 1 is a vertical sectional view through the burner, illustrating my invention. Fig. 2 is an elevation of the burner, showing two globe-holders with the upper holder carrying a globe. Fig. 3 is a view similar to Fig. 2, showing the upper globe-holder removed and the under holder carrying a different-style globe from that shown in Fig. 2. Fig. 4 is a plan view of the wire-gauze cap. Fig. 5 is a side view of the wire-gauze cap. Fig. 6 is a perspective view of the regulating-screw detached, and Fig. 7 is a plan view of the globe-holder detached.

In the drawings, A represents the body portion of the burner made in two parts A and A-, secured together by the turned flange a. The lower portion A is of hemispherical form, and the upper portion A is of conical form, truncated to form the shoulder A and the cylindrical neck A, which enters the mantle VI.

The lower portion A of the body portion of the burner is provided with radial apertures a to admit air. A sleeve a forming part of the portion A, is secured to the regulating device B, which has a small outlet passageway I) and a regulating-screw C, located at right angles to the said passage-way b. A small aperture 0 in the screw C allows the gas to pass in an undivided stream into the passage-way b. By slightly turning the regulating-screw the flow of gas may be reduced without dividing the stream of gas.

The screw C is provided with a long shank c, which enters the aperture b in the nozzle B and forms a rigid bearing for the same. The screw C has a threaded portion 0 and a shoulder 0 so that said screw can be adjusted.

By constructing the body of the burner in the above form the air and gas become thoroughly mixed in the large chamber formed by the body of the burner, and the gas is allowed to expand. The conical upper portion of the burner directs the mixed air and gas to the neck A and the mantle M and gives a light of great illuminating power.

To prevent the mantle from touching the neck A and becoming broken or turning black, I provide a cap E, made of wire mesh, with its sides fluted, as shown at 6, Figs. 4 and 5. This construction also allows the free admission of air to the mantle. The top of the cap is flat, and the usual mantle-support F is attached in the center thereof.

The burner is provided with two globeholders D and D. The lower holder D is secured by the flange a to the central part of the body A. The upper holder D is detachably secured to the neck A of the body portion. The holder D is constructed, as shown in Fig. 7, with arms d, carrying the sleeve (2. The lower holder is made in the same manner and from the same dies as the upper holder. When the holder is secured to the body A by the flange a, as shown in Fig. 1, the arms (1 and the sleeve (1 are cut away, as they are not needed.

By providing an upper holder D the style of globe shown in Fig. 2 may be used. When it is desired to use the globe shown in Fig. 3, the holder D is removed from the burner and the globe may be placed in the holder D, as shown in Fig. 3, and, as shown in dotted lines, Fig. 2, the ordinary cylindrical Argand chimney may be used in place of the globes. The globe shown in 2 requires the admission of air at the bottom. 1n the style of globe shown in Fig. 3 the air is admitted through the circular openings in the sides of the globe, and it must be closed at the bottom.

Any standard globe or chimney may be used in connection with my improved burner, making it particularly adapted for universal use.

Having thus described my invention, I claim and desire to secure by Letters Patent 1. In a burner, the combination of a body portion, a globe-holder attached to the central part of said body portion, a cylindrical neck on said body portion, a shoulder formed at the junction of the said neck and said body portion, a globe-holder adapted to be supported on the said shoulder, a mantle, and means for supplying gas to the body portion, substantially as described.

2. In a burner having a cylindrical gasoutlet neck, the combination of a mantle, a

cap adapted to fit over said cylindrical gas outlet neck, said cap having a fluted cylindrical body portion, an end portion, and said cap having perforations formed in the said fluted cylindrical body portion and in the said end portion for the free passage of gas to said mantle, substantially as described.

3. In a burner, the combination of a body portion, a mantle, a supply-nozzle attached to said body portion, said nozzle having a central passage-Way formed therein, a regulatingscrew having a smooth end ortion with an aperture formed transversely through the same, a central screw-threaded portion of larger diameter than the said end portion and a portion of still'larger diameter forming a shoulder to bear against said nozzle, and said nozzle having an aperture formed therein to receive said regulating-screw, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

WILLIAM MOLEWEE.
